Luke continued with a diatribe against the Pharisees. Luke indicated that the crowd gathered by the thousands (Ἐν οἷς ἐπισυναχθεισῶν τῶν μυριάδων τοῦ ὄχλου), so that they trampled on one another (ὥστε καταπατεῖν ἀλλήλους). This was the first mention of a problem with crowd control. Jesus then began first to speak to his disciples (ἤρξατο λέγειν πρὸς τοὺς μαθητὰς αὐτοῦ πρῶτον). He told them that they should be aware (Προσέχετε ἑαυτοῖς) of the yeast (ἀπὸ τῆς ζύμης) that is the hypocrisy (ἥτις ἐστὶν ὑπόκρισις) of the Pharisees (τῶν Φαρισαίων). This saying about the yeast of the Pharisees can be found in Mark, chapter 8:16, and Matthew, chapter 16:6, but there are slight differences. Mark and Luke did not mention the Sadducees, but Matthew did. Matthew said that Jesus told his disciples to watch out for the yeast of the Pharisees and Sadducees. Matthew had a clear rebuff of both these groups and their growing yeast, leaven, or power that was expanding, but there was no mention of the Scribes. For Mark and Matthew, this discussion took place about bread on a boat trip. The disciples discovered that they had no food when they landed on the other side of the Sea of Galilee. However, Mark said that it took place while they were still in the boat. Mark was the only one to mention Herod, the Roman appointed political leader in Galilee. Mark said that Jesus cautioned or instructed his disciples. They were to watch out for and be aware of the yeast of the Pharisees and the yeast of Herod. This was a clear rebuff of both the Pharisees and Herod. Their growing yeast, leaven, or power was expanding. Here, it is a simple warning against the Pharisees only. Do you know anybody who is a hypocrite?
